APPARATUS FOR DISPENSING LIQUIDS.

Specification of Letters Patent. Patented Sept. 29, 1914- Application fiIed June 21,1912. Serial No. 705,142.

To all whom it may concern:

Be it known that I, ADAM E. SGHATZ a citizen of the United States of America, residing at Mount Vernon, in the county of VVestchester and State of New York, have invented certain new and useful Improvements in Apparatus for Dispensing Liquids, of which the following isa specification.

My invention relates to improvements in portable apparatus or receptacle for 7 dispensing liquids under pressure, the latter being preferably provided with carbonic acid gas and has particular relation to an apparatus in which the gas container is mounted on and removably connected to the receptacle having theliquid to be dispensed.

The principal object of my invention is to provide an apparatus in which there are two chambers, one to convey the heavy chargeand the other constituting a reducing chamber of smaller capacity to convey the charge of suflicient pressure to lift the liquid. This pressure should not exceed 25 pounds, forj the reason that when the beer or liquid is subjected to a greater pressure than say about 25 pounds, the liquid is so surcharged with the gas,that it will not flow freely, but will be discharged in a foaming condition. It is also very dangerous, to allow a heavy charge of gas into the bottle as many have actually burst or exploded. By means of the reducing chamber this dangeris entirely avoided. 1

A further objectof my invention is to provide an apparatus by means of which the gas container is charged through a port controlled by a valve of ordinary type or which may be charged by means of a capsule having carbonic acid gas, in which case the head or gas container may be recharged without a special apparatus. The space formed between the walls of the container may be charged with hot or cold air, or the said spaces may be filled with asbestos or other non-conducting material.

Another object is to provide an apparatus which is simple and eflicient in operation, durable in construction, of sufficient strength to resist explosion, readily applied or re moved, and which maybe manufactured, at a relatively low cost.

The foregoing and such'other objects as may occur from the ensuing description, are attained by the improvedconstruction, com-. bination and arrangement of partshereinafter fully described and illustrated in the accompanyingdrawings forming a part of this specification and particularly pointed out in the appended claims.

In the accompanying drawings in which similar reference characters indicate similar parts in each of theiviews :--Figure1, represents a central longitudinal sectional view of one form of my apparatus applied to a liquid container, showing the gas heador chamber anda reducing chamber. Fig. 2,

is a transverse sectionalview taken on the line 2+2, Fig. 1. Fig. 3 is a detail view partly in section showing the means for actuating the valves shownin Fig. 1.

In theform shown in Figs. 1 and 2,1 have designed a containerjespecially adapted for the use of tourists and automobilists, since they can'be made of any suitable size, preferably of a gallon capacity. Personstraveling may always be provided with a cool or hot drink. For hospital use and in the. sick room my improved containers are of. great practical use.

'As illustrated in Fig. 1 of the drawings,

a double vessel is shown. In this form the inner vessel may be of glass or where great strength is requiredmay be made of metal,

0 9;forming the reducing chamber 10, and

seated in a recess formed in the lower-portlon of said casing 9, 1s a washer 11 against .which the upperfportion or neck of the inner vessel is adapted'to rest. The upper portion of the casing is screw-threaded at 12 to which is secured thelower threaded end 13 ofthehead or main gas-chamber 14, the latter being provided with a screw-thread ed capfor. cover 15 and a valved inlet 12* through which the chamber 1 1 may be filled with gas in case a capsule is not used. At one. side of the chamber 1 1 is an outwardly extended screw-threaded portion 16 and ah inwardly extended portion 17 forming a chamber within which is placedv the gas to close the seat 23, by means of a coiled.

spring 26 positioned on the rod 25, between an extension 27 formed on the inner end of the casing of the capsulev and the valve 24,,

the lower portion of the valve rod 25 extending into the smaller or reducing chamber 10. The latter chamber has a diaphragm 28 provided with a valve seat 29, said seat being'normally closed by a valve 30 provided with a valve stem 30*extending upwardly intothe chamber-1O and downwardly through the. bottom portion 31 of the casing 9, said valve '30 being positioned on the lower side of the valve seat and held seated; by a coiled spring surrounding the valve stem between the lower portionof the said valve 30, and the bottom portion 81 of thecasing 9. The bottom of said casing being provided with an opening 32 through which the gas is admitted to the inner vessel. Extending through one side of the casing 9 and into the chamber 10 is a cam 33 carried by a rotatable key 34-, the movement of said cam in one direction opening the valve 24: and permitting the gas to pass into the lower or reducing chamber 10, and by moving the said cam in an opposite direction the valve 30 is opened, and gas thereby admitted to the inner vessel, hence the lower end of the valve rod 25 and the upper end of the valve stem30 being on opposite sides of the cam, thesaid valves 24 and 30 may be operated successively but not simultaneously, as is clearly shown in Figs. 1 and 4. By this latter. construction communication between the innenvessel and the main gas-chamber let can only be had through the smaller or reducing chamber, the ports to which'cannot ,beopened simultaneously when-the parts are in position.

.It will lee-understood that the pressures in the two chambers need not be equaLt'hat in the reducing chamber being simplythe pressure required to discharge the contents of the inner vessel, the pressure in the reducing chamber being increased by manipulating valve 24: when. necessary,

In the form of the construction shown in Figs. 1 and 2, the apparatus is so shaped and arranged as to rest on the side instead of the bottom. For securing this result, the

members 1 and '2 have one side fiat, while reducing chamber and the dispensing tube 4 is curved in the direction of its length to cause it to be properly positioned within the inner member 1, said tube extending to the spout lel the latter being located at the end of the main gaschambcr 14, instead of on the side. This structure of Figs. 1 and 2 being especially useful in automobile service, alii'ording a greater base support.

As will be readily perceived in the construction shown the receptacle and its head or pressure apparatus are complementally formed so that the securing in position of the parts of the apparatus completely isolates the chamber surrounding the inner member of the receptacle, the securing operation firmly positioning the inner member relatively to the outer member. Furthermore, the parts are arranged to permit of ready assemblage, and are of simple construction permitting of the formation 01'' parts of maximum strength to resist usage and liability of explosions.

Having thus described my invention what I claim and desire to secure by Letters Patent is 1. A. liquid dispensing apparatus comprising a vessel, a gas head connected to said vessel having an upper main gas ehamber provided with an auxiliary chamber formed in one side thereof for the reception of a gas charged capsule, a reducing cha1nber intermediate said main chamber and vessel, a valve connected with said main chamber, a valve connected with the reducing chamber, and means carried by the reducing chamber and extending within the same for successively operating each valve to regulate the pressure supplied to the vessel containing the liquid. 2. A liquid dispensing apparatus comprising a vessel, in combination with a gas containing head, said head having an upper main gas chamber provided with an auxiliary chamber formed in one side thereof for the reception of a gas charged capsule, a reducing chamber intermediate said main chamber and vessel, a valve connected with said main chamber, a valve connected with the reducing chamber, means carried by the projecting into the same for successively operating such valves to regulate the pressure applied to the vessel, and a discharge tube passing from the vessel entirely through the reducing chamber and main chamber and projecting through the top of the latter chamber.

In testimony whereof I here aflix my signature in presence of two witnesses.
